Enter Bootloader mode in our Custom Project - nrf5340

[Jagan K]

Hi,

   We have been using the DeviKit for our initial development and now we have developed our own custom board using the nRF5340. I trying to flash the device, but couldn't enter the Bootloader mode, even after asserting the P0.18 to low during RESET.

I am trying to flash using UART. Is there any-other pin that needs to be controlled to enter the boot loader mode?

Hello,

In the image attached, I can see some communication between the terminal and your custom board. Could you tell me exactly what issue you are facing?

Kind Regards,

Hi,

Actually we done the boot build for our custom board and flashing the file in our board via Seggar.

After flashing, we are checking the log messages in UART1(P1.00 & P1.01) lines. In that we are getting the above message.

Also, we checked for log messages in other UART2, no messages were found. The thing, we would like to know that we done the Build configuration correctly or not?

Attached the "Waggle_boards.7z" build file for your reference.

Thanks,
